A Japanese Language Proficiency Test is a bit out of our scope. We built Drops mainly to encourage users to learn a wide variety of words in a foreign language. Our app is a complementary tool as it provides a building block to enhance vocabulary.

We’ll discuss your idea with the team anyways, and we’ll see what we can do.

Just want to add that I too think this would be a valuable feature! Organizing vocabulary by frequency of use (eg. JLPT N5, N4, …) rather than by topic would help me feel like I’m memorizing the right words. Alternatively, being able to create custom lists of words would help me focus specifically on words that I’m learning in class.
